 SCP-249 appears to be a windowless door. SCP-249 does not lead to the other side of the doorway, but to a random door within 850 meters. Items that go through SCP-249 are teleported to that other door, regardless of what may be between the door and SCP-249. When observed from the destination, the exit door appears to open on its own accord, and whatever goes through SCP-249 appears out of thin air. When opened, SCP-249 takes on the appearance of the door it is connected to. When shut, SCP-249 is no longer connected to that door and reverts to its standard appearance.
